HEAD-REST.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application iiled November 11, 1908. Serial No. 462,116.

To all whom it may concern:

Be it known that I, MASON Gr. WORTH, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Head -Rests, of which the following is a specification, refer ence being had therein to the accompanying drawing.

This invention relates to a head rest, and particularly to an attachment applicable to bed frames in which the rest is raised and adjusted by a spring connection adapted to be conveniently controlled by the person o-ccupying the bed.

The invention has for an object to provide a novel and improved construction of head rest wherein the raising spring and rest supporting arms are mounted upon a single member together with the holding device for said arms, and a tension controlling device for said spring, thus providing a simple, compact and eliicient construction whereby the rest may be raised to any desired elevation and there locked in position by the occupant of the bed.

A further object of the invention is to adjustably mount the rest upon its supporting` arms so that it may be used as a table or disposed at any desired inclination relative to the arms.

Other and further objects and advantages of the invention will be hereinafter fully set forth and the novel features thereof defined by the appended claims.

In the drawing :#Figure 1 is a side elevation showing the rest applied to a bed frame;

. Fig. 2 is a vertical section on line 2 2, Fig.

1; Fig. 3 is an enlarged section on line 3-3, Fig. 4; Fig. 4 is an elevation of the mounting casing with the outer cover removed Fig. 5 is a vertical section on line 5-5, Fig. 3; Fig. 6 is a detail of the supporting bearing carried by the casing for the several parts.

Like numerals refer to like parts in the' several views of the drawing.

The numeral 10 designates a bed which may be ofI any desired construction or configuration and provided with side rails 11 of the usual character to which this invention is applied at opposite sides as an attachment thereto. The attachment comprises a supporting plate or casing 13 provided with laterally projecting lugs 14 adapted to embrace the bed rail 11, as shown in Fig. 2, one of these lugs being provided with a clamping screw 15 by which the parts are heldin position. This plate or casing is provided at its upper portion with a slot or opening 16 extending for a portion of its circumference in order to permit a proper swinging of the rest supporting arms 17 mounted therein. This arm 17 is loosely mounted upon the bearing 18 which is threaded at 19 into the plate 13 and may, if desired, bev formed tubular, as shown in Fig. 4. The lower end'20 of the supporting arm is loosely mounted to rotate or oscillate on its bearing, while secured to the bearing directly adjacent to the arm pivot is a toothed holding rack 21 which may be provided with any desired number of teeth 22 consistent with the arc of travel of the arm 17. This arm directly above the rack is provided with a laterally deflected portion 23 through which the rod 24 of the locking pawl 25 extends, this rod being provided with an operating handle 26 in convenient position for movement by the occupant of the bed. The pawl 25 is provided with one or more teeth to engage those of the holding rack, and is held in such engagement by a spring 27 extending between the under face lof the portion 28 and the top of the pawl.

When this pawl is removed from engagement with the rack 22 during the swinging movement of the arm it travels in an arc parallel with that of the holding rack. The upper end of the arm 17 is provided with a head rest 28 which is pivoted thereon for adjustment at any Adesired inclination and held in its adjusted position by a suitable tension device at its pivot, for instance, the thumbnut 29. This rest may be provided for service in different positions so that when thrown into a horizontal position, as shown by dotted lines in Fig. 1, it will form a convenient bed table directly in front of the occupant of the bed.

For the purpose of automatically raising the rest supporting arm 17 to any desired elevation, a spring'of any desired character may be disposed .within the casing, for instance, a flat coiled spring 30. This spring is attached atone end to a pin 31 extending laterally from the lever, and at its opposite end is secured at 32'to a sleeve 33 rotatably mounted upon the pivot 18. This sleeve is provided with an operating head or handle 34 by which the tension of the spring may be adjusted through a rotation of the sleeve' tension thereon will raise the head rest to the desired elevation at which position it may be locked by releasing the rod of the locking pawl,'and the arc of travel of this supporting arm is sufficient to allow the rest to be used either as a head rest at the back of the occupant of the bed, as shown in Fig. 1, or as a table beforeY him, as shown by dotted lines in that figure. The tension of this raising spring may be increased by rotating the sleeve upon which it is' mounted which sleeve is held in position by the cooperating ratchet and pawl, and the tension may be released or p reduced by a proper operation of this pawl.

It will be seen that the invention presents a simple, compact and efficient form wherein the spring is disposed directly upon the pivotal axis of the rest arm thereby permitting the mounting of the parts in a casing of simple and convenient form adapted for direct application to the side rails of a bed and not requiring any other connection therewith. The spring casings being deected on opposite sides and connected to the head rest, as shown in Fig. 2, can be readily removed and replaced at any time, and are applicable to any character of bed, or other furniture to which it maybe desired to apply them.

Having described my invention and set forth its merits, what I claim and desire to secure by Letters Patent is 1.
